To'all whom it may concern:

Be it known that I, MAX M. SCHNEIDER, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Electric Wiring for Railway-Cars, of which the following is ,a specification.

My invention relates to electric wiring for railway cars, and refers particularly to a sgstem of wiring in which the conduits for t e wires are arranged in the car in a novel manner. 1

Heretofore it has been customary to place conduits for the electric wiring used for lighting railway cars along the roof and to tap off branch wires as necessary in order to supply current for the individual lamps. This construction has many disadvantages, inasmuch as by placing the conduits on the roof of a' car they are subjected to the action .rectly beneath the eaves.

of the elements with the consequent liability of deteriorating the insulation and causing a short circuit. Moreover, it has been a matter of considerable difficulty to lead the wiring from the'center conduit on the roof of the car to the individual lamps located both on the sides of the car and on the inside of the roof. In my improved construction, on .the other hand, the electric mains pass along the sides of the car di- These wires are contained within pipes or other suitable conduits when passing between pier posts, but when passing through such posts, the posts themselves act as the conduits and protect the wires from the action of the elements. Special means for fastening the conbe apparent to those skilled in the art that by this improved construction, I obtain several advantages. The amount of conduit which is used is considerably less than in the old construction, inasmuch as in the manner explained above no conduits are required where the main conductors pass through the pier posts; since the main conductors are contained within conduits be-' tween the pier posts, and as they pass through the pier posts the same act as conduit-s, it will be apparent that the electric mains are thoroughly protected from the action of the elements; the cover plates of the pier posts do not extend upwardly so that their upper edges are in contact with the roof, but a slight space is left for the purpose of aiding ventilation and to enable a workman to obtain access to the insulated Wires passing through the pier posts. These and other advantages of my invention will be more apparent by reference to the accompanying drawings which show apreferred embodiment of my improvements and in which:

Figure l is a fragmentary side elevation of a car equipped with my system of electric wiring. Fig. 2 is a fragmentary transverse vertical section on the line 2'- 2 of Fig. 1. Fig. 3 is an enlarged fragmentary side elevation and partly sectional View looking toward the inside of the car, and taken on the line 3-3 of Fig. 4. Fig. 4 is a vertical transverse section on the line 4-4 of Fig. 3. Fig. 5 is an enlarged fragmentary horizontal section taken through the upper portion of one of the pier posts directly below the eaves.

The railway car 10 is provided with the outer sheathing plate 11 and the inner plate 12, these plates extending upwardly and either integral with or connected to the outer plate 13 and the inner plate 14 respectively, of the lower deck 15. The inner plate 14 of the lower deck' is also continued upwardly forming the inner plate 16 of the portion of the car between the lower deck 15 and the upper deck or roof 17. As mostclearly shown in Fig. 4, the roof 17 is bent downwardly at 18 to form the caves of the car. Plate 19 is located within the roof 17 and is connected with inner plate 16 in order to form an adequate connection between the roof and the side of the car.

Riveted to the inside plate 16 are the angle irons 20,20 between which are formed the pier posts 21. These angle irons, as

most clearly shown in Fig. 4, pass upwardly and have their longitudinal flanges bent outwardly inorder to occupy a pos1t1on beneath the inner plate 19 of the roof, as shown at 22. Riveted to the outwardly extending flanges of these angle irons is the cover plate 23 which forms the outside of the pier post .21. It will be apparent that a space is left between the upper edge of the outer portion of the cover plate 23 and the roof of the car, this space being for the purpose of allowing access to the insulated.

. angle iron 20, and the opposite side thereof is engaged by the nut 29 thus securing the pipe 26 securely in position.

It will be noted that the insulated wires 24 extend longitudinally of the car on each side thereof passing through pipes 26 between the pier posts and through the upper portions of the pier posts themselves. The overhanging portion 18 of the roof 17 prevents the access of the elements to these wires.

Individual wires of the series of conductors 24 may be led off as desired in order to supply individual lamps. For example, the wires 24 are led downwardly and pass through the pipes 30 which are held in position on the brackets 31 by means of the nuts 32 and 33 engaging the ends of the pipes and between which the outwardly extending flanges of the brackets 31 are located. It will be seen that the brackets 31 are secured to the angle irons 20 by means of the rivets 34. Other wires, as for example, 24 may be led from the main series of wires 24 to the pipes 35, the ends of which are secured to the plates '16 and 19 by means of engaging the same between the caps 36 and the nuts 39. The wires 24*, after passing through the pipes 35, lead to the central lamps 38 located beneath the inner roof plate 39 of the car. As most clearly shown in Fig. 2, the wires 24, after passing through the pipes 30, lead to the lamps 40 which may be suitably located to supply light to the upper berths, and the lamps 41 similarly located to supply light to the lower berths.

As best shown in Fig. 1, the upper car windows 42 are located between the pier posts 21. The letter-board 43 passes longitudinally of the car outside of the cover plates 23 of the pier posts' 21.

It will be evident to those skilled in the art that many changes might be made in the detailed construction of the improvements which Ihavc described without departing from the spirit of my invention.

What I claim is:

1. In a railway car, the combination of a car frame having a roof therefor, an inte ral portion of said car frame being forme to afiord protection for an electric conductor passing therethrough, and a conduit opening into said protecting portion of the car an extending along the exterior of said car below the eaves, substantially as described.

2. In a car, the combination of a plurality of hollow pier posts, a conduit extending between the sides of said pier posts and communicating with the inside of the same, and an electric conductor passing through said conduit and said pier posts and protected thereby, substantially as described.

3. In a railway car, the combination of a plurality of hollow pier posts, a conduit extending between the sides of adjacent pier posts and communicating with the interiors thereof, and an electric conductor passing through said pier posts and said conduit and protected thereby, substantially as described.

4.
